miRNAs expression in HepG2 hepatocellular carcinoma cell lines: Vector Control vs. Twist1, Bcl-2, and Twist1/Bcl-2 Transfected

Project description:miRNAs profiling of HepG2 cells comparing vector-control treated HepG2 cells with HepG2 cells transfected with Twist1, Bcl-2, and Twist1/Bcl-2 plasmids. Microarray analysis revealed a panel of miRNAs with significant differential expression among these four HCC cell lines.

Effect of Twist-box mutation on gene expression induced by Twist1 overexpression

Project description:Twist1 is a transcription factor that induces EMT and drives metastasis in prostate cancer. We examined global gene expression in Myc-CaP mouse prostate cancer cells following overexpression of Twist1 and the Twist1 mutants F191G, AQA, and DQD. 15 total samples were analysed, with 3 replicates of 5 groups: Twist1-WT, Twist1-AQA, Twist1-DQD, Twist1-F191G, and vector control. We performed the comparisons: WT > VEC, F191G > VEC. Samples were normalized by Twist1 expression in addition to normal

ChipSeq of Twist1 and YY1 in PLC-PRF-5 cells

Project description:Epithelial–mesenchymal transition (EMT) is an important mechanism of metastasis and malignant progression of hepatocellular carcinoma (HCC). However, the transcriptional regulation mechanism of EMT remains poorly understood. Some transcriptional co-activators can form phase-separated condensates at super-enhancers that compartmentalize and concentrate the transcription apparatus to drive robust gene expression. Here, we demonstrate that Twist1 and YY1, interact with p300 and form phase-separated local high-concentration interaction hubs at super-enhancers of miRNA-9 and activate its expression to induce EMT and promote the malignant evolution of HCC. Phase separation disrupted by metformin perturbs Twist–YY1 condensates, thereby inhibiting EMT. To explore how the Twist1 complex regulates miR-9 expression by binding SE region, we performed Twist1 ChIP-seq combined with H3K4me3, H3K4me1, H3K27ac, DNAse, p300, and YY1 ChIP-seq data to detect the SEs of miR-9. After metformin treatment, the peak of Twist1/YY1 on miR-9 SE decreased. Metformin specifically affects the binding of Twist1/YY1 to the miR-9 SE region. 1,6-hexanediol, as an aliphatic alcohol, can weaken hydrophobic interactions and inhibit liquid–liquid phase separation by disrupting hydrophobic interactions. In order to prove Twist1/YY1 interaction at these sites requires phase separation, we detect the accessibility of miR-9 SE regions in 1,6-hexanediol-treated cells. The result showed a general decrease in the accessibility of miR-9 super-enhancer regions in 1,6-hexanediol-treated cells and Twist1 / YY1 combines the SE region of miR-9 in the form of phase separation.

TWIST1 methylation by SETD6 selectively antagonizes LINC-PINT expression in Glioblastoma multiforme

Project description:Glioblastoma multiforme (GBM) is the most common and aggressive malignant brain tumor among adults, which is characterized by high invasion, migration and proliferation abilities. One important process that contributes to the invasiveness of GBM is the epithelial to mesenchymal transition (EMT). EMT is regulated by a set of defined transcription factors which tightly regulate this process, among them is the basic helix-loop-helix family member, TWIST1. Here we show that TWIST1 is methylated on lysine-33 at chromatin by SETD6, a methyltransferase with expression levels correlating with poor survival in GBM patients. RNA-seq analysis in U251 GBM cells suggested that both SETD6 and TWIST1 regulate cell adhesion and migration processes. We further show that TWIST1 methylation attenuates the expression of the long-non-coding RNA, LINC-PINT, thereby suppressing EMT in GBM. Mechanistically, TWIST1 methylation represses the transcription of LINC-PINT by increasing the occupancy of EZH2 and the catalysis of the repressive H3K27me3 mark at the LINC-PINT locus. Under un-methylated conditions, TWIST1 dissociates from the LINC-PINT locus, allowing the expression of LINC-PINT which leads to increased cell adhesion and decreased cell migration. Together, our findings unravel a new mechanistic dimension for selective expression of LINC-PINT mediated by TWIST1 methylation.

TWIST1 expression is associated with high-risk Neuroblastoma and promotes Primary and Metastatic Tumor Growth

Project description:In this study, merging in silico transcriptomic data and in situ TMA studies, we first highlighted the clinical significance and the value as prognostic factors of the embryonic TFs TWIST1 and TWIST2, thus linking their level of expression with the outcome of NB patients. Secondly, using NB cells knocked out for the TWIST1 protein, we studied the biological impact of TWIST1 in tumors xenografts. The expression of TWIST1 was associated with enhanced primary and secondary tumor growth capacity in immunocompromised mice. Furthermore, tumors expressing TWIST1 were portrayed by a more aggressive phenotype, characterized by the presence of spindle shaped cells and the destruction of the ECM collagen fibers. Finally, the transcriptional signature deregulated by TWIST1 was found to have a clinical significance in human primary tumors and resulted to be able to activate the TME in ortho-derived xenograft. This dataset reports analyses that studied the impact of knockout of the TWIST1 protein on the secretome of the neuroblastoma cell line mentioned above.
